Hey everyone, I finally got my duet working on my upgraded ender 3 but I've been having the same issue for the past 3 days and just can't get it working.

I have a duet 2 wifi with a BL touch sensor.

I've set the Z offset following betrue3d's guide. When I home the Z axis then go to Z0, the nozzle is at the right height, but when I run the mesh grid compensation and then try to print something, the nozzle is always around 0.5mm too high off the bed.

-Z babystepping won't work because the nozzle won't move past Z0.
-Setting a negative Z offset in slic3r doesn't do anything.

I'm completely lost and don't know whats causing this issue...
Any help will be appreciated,
Andrew
